My laptop crashes (which is another question) and when it does so it swiches to a text console and outputs an error which is too long to type (like this). I can't do anything with it other than sometimes restart X (otherwise restart the computer) when it crashes. Is there any way I can get this error so I can post it? A log somewhere?
I've tried SSH and conspy, but networking seems to get cut off.

If you start a new X session, the message you are looking for is probably in /var/log/Xorg.0.log.old I suggest you paste the entire file (it's a long paste) and not the part that looks relevant to you.
